Low-Dose Rituximab May Be Cost-Effective for Myasthenia Gravis

December 28, 2019

Autoimmune myasthenia gravis is typically treated with surgery, acetylcholine esterase inhibitors, corticosteroids, and immunosuppressive drugs like azathioprine and mycophenolate mofetil. Some patients have refractory disease and may require therapies like eculizumab (Soliris), which, while effective, is a particularly high-cost biologic that has no approved biosimilars in Europe or the United States, although biosimilars are advancing through clinical development. Rituximab, however, which is lower-cost than eculizumab and has multiple approved biosimilars, has also emerged as a promising treatment.
